Origin Story

Red Leaf Lettuce emerged through traditional selection and breeding of loose-leaf cultivars, with commercial varieties featuring red pigmentation appearing globally since the mid-20th century. It does not trace to a single breeder but represents a group of cultivars developed over time.

Classification

Belonging to the species Lactuca sativa var. crispa, Red Leaf Lettuce falls within the leaf lettuce horticultural group, distinguished from head types like Iceberg or Butterhead by its loose, open rosette form.

Appearance or Form

This lettuce forms loose rosettes approximately 25 cm in diameter, with leaves that transition from green at the base to red, burgundy, or purple at the tips due to anthocyanin pigments. The leaves are tender with ruffled or frilled margins, creating an attractive, colorful appearance.

Behavior or Usage

Primarily consumed fresh, Red Leaf Lettuce is favored for salads, sandwiches, and garnishes where its mild, slightly sweet flavor and striking color add visual and taste appeal. It is marketed as whole heads, loose leaves, or as part of mixed salad blends, but is rarely cooked to preserve its texture and color.
